Aluminum Sulfate Fertilizer: The 12-0-0 Wonder

What is Aluminum Sulfate Fertilizer?

Aluminum sulfate is an inorganic compound with the formula Al2(SO4)3. It is used as a flocculant in water treatment plants, as a mordant in dyeing, and as a fertilizer. As a fertilizer, aluminum sulfate is used to lower the pH of soil, making it more acidic. This can be beneficial for plants that prefer acidic soil, such as blueberries, azaleas, and rhododendrons.

Benefits of Using Aluminum Sulfate Fertilizer

• Lowers the pH of soil, making it more acidic
• Improves the availability of nutrients in the soil
• Helps to prevent root rot and other diseases
• Can be used as a foliar spray to control pests and diseases
• Can help crops to tolerate drought conditions

How to Apply Aluminum Sulfate Fertilizer

Aluminum sulfate fertilizer can be applied to the soil in several ways. It can be broadcast over the surface of the soil and then watered in, or it can be dissolved in water and applied as a foliar spray. The amount of aluminum sulfate fertilizer to apply will vary depending on the pH of the soil and the type of plants being grown.

When applying aluminum sulfate fertilizer as a soil amendment, it is important to follow the directions on the package carefully. Over-application of aluminum sulfate fertilizer can damage plants and make the soil too acidic.

Tips for Using Aluminum Sulfate Fertilizer

• Test the pH of your soil before applying aluminum sulfate fertilizer. The ideal pH for most plants is between 6.0 and 7.0.
• Do not apply aluminum sulfate fertilizer to plants that are already growing in acidic soil.
• Apply aluminum sulfate fertilizer in small doses, and gradually increase the amount as needed.
